surface area = 4 x pi x r^2
diameter = 1 so radius = 1/2 = 0.5
4 x 3.14 x 0.5^2 = 3.14 meters^2
Answer:
Yes.
From Definition - A special relationship where each input has a single output.
Check if there is going to be one y for one x.
Step-by-step explanation:
- Re-write it in terms of y=…., meaning solve for y
- If it looks like you have two equations then it is a relationship -case a
- If you need to prove that one has a function for case b, you would point out that if you substitute any value you will get some value in Reals.
